ALBERT BEZNER, OF RAVENSBUBG, GERMANY.

SORTING-MAGHINE.

To all whom it may concern Be it known that l, ALBERT BEZNER, a citizen of the German. Empire, and residing at Ravensburg, Wurttemberg, Germany, have invented certain new and useful lmprovements in Sorting-hlachines, of which the following is a specification.

My invention relates to a swing sorting machine for sorting or screening both dry material, e. g. the disintegrated wood for cellulose manufacture, and also wet or liquid-like materials, 6. 9. wood particles suspended in water, cellulose, or paper-pulp.

The new sorting machine operates similarly to the flat sitter well known in the milling trade, 2'. e. by means of a swinging motion given to the sorting chest. Owing to this swinging motion the material while being sorted is given a motion over the sieves or toward them of a loop-like form, while propelling boards or metal plates give a continual forward movement to the said material.

The novelty of my invention consists in the provision of a sorting chest which is of .mechanism in this space it is possible to apply in known manner the driving power directly at the level of the center of gravity of the chest. When admitted, the material to be sorted is divided by means of one or more vertical partitions into two, four or more parts, half of which parts runs through the one half. and half of which parts runs through the other half of the sorting chest, the material of each grade having a common outlet located at a part of the ring opposite the inlet. The advantage so obtained is that large quantities of the material to be sorted can he dealt with in a comparatively small machine.

Owing to the crank-pin being applied at the level of the center of gravity, my ma- My new sorting machine moreover gives the advantageof compact construction, in that the mecha sm. t rai rsa s pp Specification of Letters Patent. I Pat nt Jan. 2 1 5;

very much simplified. Concerning the other features of the sorting machine, in particular concerning the arrangement in these machines ot the vertical sorting walls designed for use with wet material requiring sorting, and concerning the special means effecting the transmission of motion, detailed particulars will be hereinafter given.

Several illustrative embodiments of my invention are represented by 'way of example in the accompanying drawings, wherein Figures 1 to 3 relate to the first form of sorting machine; of these figures Fig. 1 is a side elevation partly in section, Fig. 2 a plan, also partly cut away and Fig. 3 a sectional view showing the suspension device for the chest; Figs. 4 and 6 relate to a second form of sorting machine; of these figures Fig. l is a side elevation partly in section, Fig. 5 a vertical section of the admission chamber for the material to be sifted and Fig. 6 a plan of said chamber; Figs. 7 and 8 relate to a third form of sorting machine, Fig. 7 being an elevation partly in mg and driving the sorting chest becomes section and Fig. 8 a plan partly in section;

and Figs. 9 and 10 relate to a fourth form of sorting machine, Fig. 9 being a vertical section and Fig. 10 a horizontal section on the line AB in Fig. 9.

Referring to Figs. 1 and 2. 1 is the frame o1 the sorting machine. this frame journaling the shaft 2 carrying the flywheel 3. The crank pin 4 fast on the flywheel engages in a cross 5 around which the sorting chest 6 is rigidly mounted in such a way that the horizontal plane containing the center of gravity of the chest transversely bisects the pin 4. In the corners formed by the inside walls 7 of the sorting chest are. located corner-brackets 8 carrving'bearings 9 for the lower ball-ended pins 10 of the suspensions 11 (see Fig. 3). Mounted on the frame 1 are four columns 12 carrying. rigidly fixed at their upper ends. the second cross 13. The four corners of this cross 13 run out into brackets 14 carrying the bearings 15 (Fig. 3) for receiving the hall-ended pins 16 of the suspensicn',,11. The sorting chest has four vertical inside walls 7. four vertical outside walls 17, a bott m 18 and a cover 19. as well as the sliding sieveframes 20. 20. The sieve-frames 20 have a la ger mesh thanthe sieve-frames Q0. The

admission chamber 22 for the sorting chest 6 is subdivided by means of the partition 23. One half of this chamber is arranged to lead the material along the track 26 of the sieve-frame 20, the other half to lead it along the track 27 of the sieve-frame 20. There are also arranged, in each case-to suit the direction of rotation, propelling blades 2- and 25, the former in one half of the chest on the inside walls 7 and the latter in the other half on the outside walls 17. From the admission chamber 22 the two tracks 26, 27 run over the sieve 20 to the outlet 28. The outlets are so arranged that the various grades of the sorted products remain separated one from another, the same grade of product from the same sieves issuing however together at 28, 29 or 38. The shaft 2 is driven by means of the pulley 30, and the motionis transmitted by the crank-pin 4 and the cross 5 to the entire sorting chest 6, which is thus given a circular swinging motion with corresponding pendulous motions of the suspensions 11. The material being sorted is moved forward in the tracks 26, 27 on the sieve 20 by means of the propelling blades 2% or 25 to the outlet 28, only the coarsest grades thus reaching this outlet 28; on the other hand the grades of medium fineness tcgether with the finest grades fall onto the sieve 20. Of the material covering the sieve 20 the grades of medium fineness reach by means of corresponding "propelling blades in the two tracks, the outlet 29. The finest grades which have fallen through the sieves 20, 2 are thus completely separated from the remaining constituents of the original material.

The second form of machine, as illustrated in Figs. 4 to 6, differs from the above described solely in that the admission chamber has two cross partition 23, 23 and therefore four inlets 31, 32, 33, 34: separated one from another. Moreover two sorting chests 6, 6 are arranged one over the other, each being provided with two sieves 20, 20, 20", 20'. Here the sieves 20, 20 have the same mesh, and likewise the sieves 20", 20". The material to be sorted passes into the inlets 31, 32, 33, 34 of the common admission chamber 22, and half of it thus passes to the two separate tracks on the sieve 20, and the other half to the two separate tracks on the sieve 20". The two halves of the material being sorted are then sorted out in the same manner as in the first form of machine described and the products of the same fineness are led together to the same outlets. What remains above the sieves 20, 20 issues at the outlets shown at the left of Fig. 4, while what remains above the sieves 20, 20", issues at outlets at the rear which are not shown in Fig. 4. The finest product after falling through the sieves 20 a d 20 re he th Outle s 3. 6 i t common junction=pipe 3'7: Of "course-j unetion-pipes may also be provided for the other pairs of outlets.

The form of machine just described indicates that by providing a suitable number of partitions in the admission chamber the whole of the material to be sorted can be divided in a desired mannerfand particularly that the said material can be distributed instead of on one or two, also on several, sieves of the largest' 'ineshand from these can be sorted by means of several sieves of continually dimlnlshing grades of each end an eccentric 43 running in anoilbox 4-2. Owing to the rotation of the eccentries, the oil-boxes are driven to and fro in directions transverse to the axis of rotation. Since however those outer surfaces of the eccentrics which are radialto the said axis are not in a rectilinear plane at right angles thereto, the abutment pieces 4%- acting on these surfaces simultaneously give to the oil-box 42 a to-and-fro motion in directions at right angles to those of the motions just described. pendent upon the cooperation of the two eccentric motions and on the form of the eccentrics can be obtained which differs in desired manner from a circular motion.

It is evident that a motion de- This is a consideration of importance in the wet sorting machine hereinafter described.- The oil-boxes 4-2 are supported on balls 39 (Fig. 7) which run in grooves 50.

The fourth form of sorting machine, as illustrated in Figs. 9 and 10, differs from those hereinbefore described in being suitable not for dry but for wet material and in having not horizontal but vertical sievewalls. As seen in Figs. 9 and 10, 6 is the ring-shaped sorting chest which has the divided admission chamber 22. Inside the sorting chest are arranged the two ring shaped, unperforated bottom-plates 45, 15 which are bounded outwardly by the vertical sorting surfaces or sieves 4-6, 461 In order to conduct the material passing through the sieve 46 to the bottom-plate 45, the inclined guide-plate 47 is arranged above the sieve 46'. Each bottom-plate 4-5, 4 5 has a suitable channel 48, 4-8 which conducts the material coming onto it back again to the place of admission before it is sub jected to the action of the propelling blades 24, 24. Above the bottom-plates 45, 45'

The wet sorting machine described is especially suitable for liquids containing bodies in suspension, such as e. 9. woodmeal, cellulose and so forth. Such liquid first falls on the unperforated bottom-plate 45, and receives with this plate a swinging motion, it is thus thrown by the propelling blades 2 against the walls of the sieve 46, and so sorted that the coarsest particles remain behind in the upper, while the finest flow away to the lower part of the machine. That portion of the material being sorted which has penetrated the uppermost sieve falls into the inclined channels 48, and, when arriving close to where it was admitted, falls from these channels onto the inclined plate 47 in order to be again subjected to the action of the propelling blades (in this case 24). The finest particles of the material being sorted penetrate the sieve 46, reach the channel 48, and, when near the place of admission, pass to the propelling blades 24", in order to finally leave the sorting chest at 38.
